Background and Challenges: Growing Data Volume and Potential 'Two Major Security Risks'

Recently, data volume handled in business, such as video content, high-resolution images, and CAD design data, has been increasing steadily. However, in workplaces where secure infrastructure development has not kept pace, 'two major risks' that could threaten the company's survival have become common.

Risk 1: Vulnerability due to PPAP (sending ZIP files with passwords)

The Japanese practice of encrypting files with a password in a ZIP file and sending the password in a separate email (PPAP) is now considered to have almost no security benefit. It is also being phased out by the government and major companies because it acts as a cover for malware infections.

Risk 2: Lack of governance due to Shadow IT (unauthorized use of personal services)

When official file transfer means provided by a company have capacity limits or are difficult to use, employees often take it upon themselves to use personal free file transfer services. This is 'Shadow IT,' and because companies cannot track who sent what to where, it has become a major hotbed for information leaks.

Solution: Zero-Risk Data Sharing with TENMA

Our service fundamentally removes these management risks. It is not just storage; it implements features to maximize operational efficiency while strengthening corporate governance.

'Secure URL Sharing' to eliminate PPAP

Large volumes of data can be sent and received safely just by issuing a dedicated share link (URL). It eliminates the inefficient process of ZIP compression and sending separate passwords, ensuring data delivery through encrypted paths.

'Administrator Control and Log Management' to prevent Shadow IT

It allows for mandatory password settings, download expiration dates, and access count limits for shared URLs, while recording all access logs in real-time. By providing employees with a 'safe and easy-to-use official tool,' it breaks dependency on dangerous external services and builds a strong governance structure.

High Operability for Company-wide Adoption without Training

No matter how robust the security, if it is complicated to use, employees will turn to Shadow IT. TENMA pursues an intuitive interface so that it can be used immediately regardless of IT literacy, standardizing security levels from the moment of introduction.

Future Prospects

Through the provision of 'Cloud TENMA,' Replus Inc. will eliminate the 'PPAP problem' and 'Shadow IT risk' faced by Japanese companies, powerfully promoting safe and sustainable Digital Transformation (DX).
